ok so i know that to change the shift knob all you have to do it pull up until it pops out.

so when i get my new one, i just push down and bang it into place, right?
how many people have had problem of the shift knob staying in correctly? i have a feeling i wont be able to get the new shift knob to stay in tight like the stock one from the factory even though im getting a bmw shift knob.
